1'0 aZZ 'wlwm'c't may concern:

Be it known that .l, Jenn W. D. CARSLAW, a subject of the King of England, and a resident of the city of Prospect, in. the county of Jefferson and State of Kentucky, have invented certain new and useful linproi ements in Armored Inter-liners for Tires; and I do hereby declare that the following is a full, clear v and exact description of the same, reference being bad to theac companying drawings, and to the numerals of reference marked thereon, which form a part of this specification. v

This invention relates to a tubular puncture proof tire interliner member adapted to be placed within the usual basing of a pneumatic tire, and adapted to receive the air retaining inner tube therewithin, thus reducing the size of inner tube-necessary for the particular casingand, yet retaining all of the resilient qualities of the tire. The invention contemplates the construction of a puncture proof interlineror casing member adapted to receive the usual air inner tube'therein, and to be placed Within the outercasing of the tire so that the inner air tube cannot be punctured by entrance of foreign objects through the casing member of the tire. I

It is an object therefore of this invention to construct a puncture proof inner lining member or casing member for a tire adapted lit] to be placed within the usual outer casing of the tire and to receive the air inner tube therewithin to efiectually protect the air inner tube and affording a punctureproof wall between the air inner tube and the usual outer tire casing.

It is furthermore an important object of this invention to construct a built up puncture proof tire intcrliner adapted to be placed within a tire casing and embodying a series of layers of staggered squares or plates of metal, leather fiber or composition, I each spaced from the other and thoroughly vulcanized. into the structure to afford a flem ible and yieldable protective member.

Other and further important objects of the invention will be evident from the dis closure in the drawings and specification.

Thirinvention (ina preferred form) is illustrated in the drawings and hereinafter more fully described.

parts broken away, of one of the square layers of the structure shown in Fig.

As shown on. the drawings:

The reference numeral 1, indicates as a whole an outer tire d'asing of any usual and well known construction, which in the present instance is shown secured in a clencher rim 2, upon a wheel 3. Placed within thetire casing l, is a puncture proof interliner or protective member at, the edges of which are tapered at the point at which the same contact with the beads of the casing l, and within said protective interliner is an air inner tube 5. Said interliner 4:, is \built up of a plurality of layers of difierent elements and materials, shown clearly in sectional View in Fig. 5.; The outer wall or layer is denoted by the reference numeral 6, and consists of gum, rubber, or'composition. and the inner layer, which is preferably of the same materiah is denoted by the reference numeral 7. Laid next to the outer layer 6, is a fabric layer 8, and similarly, a fabric layer 9, is laid next to the innermost layer *5. Eetween the fabric layers 8 and 9, are five layers of gum or rubber, all denoted by the reference numeral 10., and interposed. therebctween are four layers of small squares or plates with those of certain layers of difal ferent size.

The plates air-squares l1; and the plates or squares 12 are substantially the same size, and the same are staggered with" their corners overlapping, as clearly shown in Fig. 3. The squares or plates 12% are smaller in site too at v

and are arranged in register with the open spaces existing between the edges of the rerangement which prevents projection of any object completely through the interliner. Although the respective square or plate members are shown separated by defined layers of material in Fig. 5,'this condition only exists when the structure is first'built up, and after vulcanization thereof, the entire structure becomes substantially a uni- .tary member, with the various layers of staggered squares or plates disposed there through.

In the modified structure illustrated in Figs. 6 and 7, 1 have shown the respective metal or square plate members which are denoted respectively by the reference numerals 15,16, 17 and, 18, as stitched between fabric layers 19, so that each plate or square element is disposed within a pocket, and said fabric layers 19, are then placed between j gum or rubber layers 20, and the entire structure vulcanized to form a unitary mem ber. The structure thus formed is flexible, yieldable and conforms to all deformations imposed upon the tire, and yet resists piercing of the inner air tube 5, by projection of any objects through the outer casing 1, of

the tire.

I am aware that the details of construction .may be varied through-a wide range without departing from the principles of this invention, and I therefore do. not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

1. The combination with a tire casing, and an inner tube, of an interliner disposed therebetween and comprising a plurality of layers of rubber, and a plurality of layers of staggered plate elements vulcanized between the layers of rubber, said layers of plate elements comprising plates of different sizes and arranged with the larger plates disposed in the outer portion of the interliner and with the smaller plates'disposed in the inner portion thereof.

2. The combination with a tire casing, and an inner tube, of an interliner disposed therebetween and comprising a plurality of layers of rubber, a plurality of layers of fabric members sewed together to form pockets and dis osed between said layers of rub-- her, an ...pl.ate members disposed in said pockets in staggered relation with respect to each other.

In testimony whereofl have hereunto subscribed my name in the presence of two subscribing witnesses.
